Using CSS and Javascript i made a piece of code that works like this:
I have a table with some pictures, when the user activates the mouseover on those, there is some javascript that hides a div and shows another, the problem is that in IEv5.0 the script doesn't work, when the mousover is activated the images slide down. (I know my english is terrible so I will post the code)

HTML and java script:
Code:
 
<body>
 
     <div id="box">
         <div id="rightbox">
            <div id="eqwrapper">
             <div id="equipa">
                 <table width="170" border="0" cellspacing="0" cellpadding="0">

CSS:
Code:
 
body {text-align:center}
h1 {margin:0px}
h1 {font:8pt Verdana,Arial,Helvetica,sans-serif; color:#000000}
h1.equipatext {color:#009600}
#box {text-align:left; margin:10px auto 0px auto; width:806px}
#rightbox {text-align:center;float:left; width:198px}
#eqwrapper {margin-right:auto; margin-left:auto; text-align:left; width:170px}
#equipa {float:left; width:170px; margin-top:10px}
.eqinfo {float:left; text-align:center; margin-top:5px; display:none; width:170px; height:50px}
.eqtip {float:left; text-align:center; margin-top:5px; width:170px; height:50px}

The script starts working fine in IE v5.0 when I remove the css containers (box,rightbox,eqwrapper) width.
